Abstract

Automatic defrosting device for deep-freezer, comprising a clock (3), a double switch for defrosting (5, 7), heating resistors (16) and a battery thermostat (22). The thermostat (22) has two triggering levels, a high one (+8 DEG C) and a low one (-28 DEG C). The high triggering level stops heating (16) and restarts cold production (12). The low triggering level also restarts ventilation (13). <IMAGE>
